Question

After 5 months of saving money, Nikki had saved $350. She has now been saving for 9 months and has saved $690. Find the percent of increase in the amount of Nikki's savings. Round the percent to the nearest tenth if necessary.

Answer 1

Answer:

21%

Step-by-step explanation:

for the first 5 months Nikki saved $350 so she saved 70 every month. for the next 4 months she saved 690-350=340, so 85 per month. The rate of increase should be (85-70)/70=.214 round it to the nearest tenth is .21, to find the percentage just multiply 0.21 by 100 you get 21%
